HANGING TYPE GRAIN RAISING MACHINE FOR CONCRETE WALL SURFACE

摘要

PURPOSE:To enable a uniform grain raising work even on a vertically long wall surface, regardless of the height thereof, by moving weight members in sequence away from the wall surface, according to the lowering of a wall surface grain raising machine hung from an upper level. CONSTITUTION:A wall surface grain raising machine equipped with a grain raising means 1, a lifting means 2 and weight members 3 and 3, are hung from an upper level between the center of gravity of the machine and a vertical wall surface P, using a hanging rope 4. Angular moment generated via the rope 4 is received with the grain raising means 1, and this means 1 is gradually lowered with the lifting means 2, while performing a grain raising work for the wall surface P. In this case, the weight members 3 and 3 are moved in a direction parting from the wall surface P, according to the lowering of the grain raising means 1. In addition, the center of gravity of the machine is kept away from the wall surface P, thereby maintaining the pressing force of the aforesaid means 1 to the wall surface P at a constant level.
